Estimation of production efficiency during sucker-rod pump operation
Ahmadov I.Z.Currently, the fields being at the last stage of development are operated mainly via sucker-rod pump units. Based on the actual field data, the regularities were studied and the impact of theoretical delivery value of pump units on the production indexes, as well as on the repair frequency and overhaul period estimated. The dependences of liquid, oil, water and waterflooding on the theoretical delivery in the whole change diapason, as well as the frequency of repairs and overhaul period of well operation on the theoretical delivery were developed. The analysis results showed that with the growth of theoretical delivery, the production parameters and frequency of repairs increase, and the overhaul period decreases. Based on the mathematical models, the estimation calculations of change rate of analyzed parameters by the intervals of actual diapason of theoretical delivery of well pumps are presented. All conducted investigations enable to estimate the economic increase limit of theoretical delivery for operated pump units.
